Is cloudy or milky water safe to drink?

Cloudy or milky-looking water can be concerning, but it’s usually harmless and safe to drink. Understanding the cause can help you determine if action is needed.

Most common cause - Air bubbles:

The most frequent cause of cloudy water is tiny air bubbles, which occur when:

• Water pressure changes in the pipes
• Cold water enters your plumbing system
• Maintenance or repairs have been performed on the water system
• There are temperature differences between outside pipes and indoor plumbing

How to identify air bubbles:

1. Fill a clear glass with water
2. Set it on the counter and wait 1-2 minutes
3. If the cloudiness clears from bottom to top, it’s air bubbles (harmless)
4. If it stays cloudy or settles to the bottom, contact us for investigation

Other potential causes:

• Sediment - May appear after water main work or high-flow events
• Hard water minerals - Calcium and magnesium are not health concerns
• Cold water phenomenon - More common in winter months
